NRF9160 Registration/Power On Budget

[Thomas]

Hi,

I noticed that if you send AT+CFUN=1 then AT+CFUN=4 more than 30 times in an hour the modem stops registering until the hour passes? Is this by design? 

Kind regards,

Thomas

Hi, Thomas!

The GSMA has specified a Radio Policy Manager (RPM) feature to protect the network from excessive signaling. In the case of connection requests(which will be initiated by CFUN=4 and CFUN=1) the default value is 30, which is also implemented in our modem firmware. Exceeding this limit will lead to a 1 hour ban from connecting to the network. You can get more details in this answer from Heidi. 

Best regards,
